Define business hours for ticket tracking? (IE Excluding weekends)

Define business hours for ticket tracking? (IE Excluding weekends)

Now that we have our entire support staff on Desk we have a KPI (key performance indicator) report setup to track resolution time. 

However the system takes weekends into account. So if a ticket is not resolved on a Friday and closed early Monday it still reports as 48hrs+ resolved time. 

Also putting a ticket "on-hold" does not pause the timer either. So say we're waiting on a customer to get us more information the system still thinks it's the Desk user that's taking forever to close a ticket.

Anyone have any ideas?
